CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims the benefit of priority toKorean Patent Application No. 10-2018-0026009 filed on Mar. 5, 2018, inthe Korean Intellectual Property Office, the disclosure of which isincorporated herein by reference.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a pipette unit for cosmetics and acosmetic container having the same, and more particularly, to a pipetteunit for cosmetics having a brush tip between a pipette and a brushmember and a cosmetic container having the same.

Description of the Related Art

In general, as a method of using liquid contents such as cosmetics,which is preferable to use a small amount of eye cream and the like at atime to use a precise quantity, conventionally, a method of individuallypackaging the contents in the form of a capsule or the like by an amountto be used for each use time was used.

However, such an individual packaging method has a problem in that it isextremely inefficient because a relatively large amount remains in thecapsule even after the user uses the contents.

In order to overcome the problems s of such an individual packagingmethod, after the contents are accommodated in the container, it isdesigned a configuration of extracting the contents every use by usingan extracting means having a general pipette or a syringe structure orusing an extracting means having a configuration of a push pump.

In the case of the extracting means having a general pipette structure,the amount of suction and extraction varies depending on the degree ofpressing a pressing portion made of rubber by the user.

In the case of using the extracting means having the syringe structure,when considering that a very small amount of about 1 ml is used, adiameter of the syringe is made extremely small or the stroke of asyringe piston is made extremely small. In addition, in order to extractthe contents, the piston of the syringe is pulled out to suck thecontents, and then the piston of the syringe is pushed again to extractthe contents.

In the case of the extracting means having a configuration of a pushpump, a certain amount of contents may be extracted whenever simplypressing a button. However, the structure is relatively complicatedbecause a structure for forming the inside and the outside of the pumpis configured by including a button, an inlet, an outlet, a spring, anda valve structure.

On the other hand, since the conventional pipette has an inconveniencein applying the contents to the skin or diluting the contents with othersolvents on the structure, an improvement measure is required.

The above-described technical configuration is a background techniquefor assisting the understanding of the present invention, and does notmean a conventional technology widely known in the art to which thepresent invention belongs.

SUMMARY OF THE INVENTION

Therefore, an object of the present invention to achieve the presentinvention is to provide a pipette unit for cosmetics and a cosmeticcontainer having the same capable of improving inconvenience of applyingcosmetics to the skin or diluting the cosmetics with other solvents.

According to an aspect of the present invention, there is provided apipette unit for cosmetics including: a brush member provided at an endof the pipette; a brush tip coupled to the end of the pipette so as tobe disposed inside the brush member and allowing the cosmetics to beintroduced or extracted into or from the pipette; and a brush fixingmember coupling the brush member to the end of the pipette, in which anexpansion portion is provided on the upper side of the brush member andthe extension portion is disposed between the end of the brush tip andthe end of the brush fixing member and coupled to the end of the pipettewith the brush tip by the brush fixing member.

The brush tip may include a fixing portion disposed between the end ofthe pipette and one side of the brush member; and an extension portionextended from the fixing portion to the other side of the brush memberand in contact with the inside of the brush member.

The extension portion may be provided to be inclined so that a width ofa region disposed at the end of the pipette is greater than that of aregion disposed at the other side of the brush member.

The expansion portion of the brush member may be provided by heating.

According to another aspect of the present invention, there is acosmetic container including: a cap portion coupled to a container body;a button portion coupled to the cap portion; a pipette of which one sideis coupled to the button portion and the other side is extended to abottom portion of the container body; a brush member coupled to theother side of the pipette; a brush tip coupled to the end of the pipetteso as to be disposed inside the brush member and allowing the cosmeticsto be introduced or extracted into or from the pipette; and a brushfixing member coupling the brush member to the end of the pipette, inwhich an expansion portion is provided on the upper side of the brushmember and the extension portion is disposed between the end of thebrush tip and the end of the brush fixing member and coupled to the endof the pipette with the brush tip by the brush fixing member.

According to the exemplary embodiments of the present invention, it ispossible to efficiently sucking cosmetics by preventing a brush memberfrom being collected when the cosmetics are sucked into the pipette by abrush tip disposed between the pipette and the brush member.

Further, it is possible to conveniently apply the cosmetics to the skinby the brush tip and the brush member and dilute the cosmetics withother solvents.

Further, it is possible to easily couple the brush member by anexpansion portion provided in the brush member and stably maintaincoupling force even during use.
